SPRING-BED.

To all whom it may concern:

Be it known that I, J. L. WHIPPLE, of Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Spring-Beds; and I hereby declare the following to be a full and true description thereof, reference being had to the drawings herewith presented, which drawings constitute a part of said description.

The nature of my invention consists in constructing and arranging the several parts of the bedstead in a peculiar form and position, by which the slats are supported in their proper relative connection while they have all the yielding elasticity required for their easy play upward and downward.

Figure 1 is a top view of the bed. Fig. 2 is a reversed view of the same showing the under side of the slats S, S, as supported on the wire springs WV, IV, and being connected by a firm strap L, which keeps all at proper distances apart, and allows them to play freely within certain limits. Fig. 3 is a view of the spring enlarged.

Similar letters denote similar parts in each figure.

It may be seen that the springW is formed of one piece of wire, having both its ends secured in the rail R, and then coiled several times around the roller 0, and thence extending over a considerable distance forming a sort of lever then crosses the slat in a transverse direction, so that the spring forms a levelbearing from 6 to w, on which the slat rests, so the slat will not be turned over by any casual impulse. The two ends of the spring are extended wide apart so as to stand bracing, and afford ample room for the slat (when pressed down) to descend without hitting on either side of the spring. The slats are prevented from moving endwise by the projections T, T, of the strap which extend through the spring and fasten to the slats.

I am aware that several forms of springs have been used for the forming elastic beds, but I have found none of them which possess the same advantages of cheapness, ease strength and durability in equal degree with mine.

I do not claim the exclusive use of springs, slats, straps or either of them separately, or in the manner and form in which they have been heretofore used but Vhat I claim as my invention and desire to secure by Letters Patent of the United States is- The general arrangement of the slat, (8,)

- the spring (VV,) and the strap (L) when constructed in the form above described, and combined for the purpose, in the position as set forth.

In testimony whereofI hereto subscribe in presence of two witnesses.
